[Intel-gfx] [PATCH] intel: Don't print messages to stderr if context creation fails.

[Kenneth Graunke]

Since there is no getparam for hardware context support, Mesa always
tries to obtain a context by calling drm_intel_gem_context_create and
NULL-checking the result.  On an older kernel without context support,
this caused libdrm to print an unwanted message to stderr:

DRM_IOCTL_I915_GEM_CONTEXT_CREATE failed: Invalid argument

In fact, this caused every Piglit test to fail with a "warn" status due
to the unrecognized error message.

Simply delete the message.  It's OK for context creation to fail.
